Work on doubling the capacity of Jebel Ali Sewage Treatment Plant is on full swing with 17% of the work in Phase 2 already completed since the start of expansion.

Eng Mohamed Ahmed Al Rayes, acting director of Sewerage and Irrigation Department, said: "The expansion work at a cost of $354m (AED1.3bn) will increase the capacity of Jebel Ali Sewage Treatment Plant from 375,000m3 per day to 675,000m3 per day."

He explained that the project consists of six phases in two main pathways, the liquid waste treatment process and solid waste treatment process, state news agency, WAM reported.

"It has a plant for the production of compost from solid waste which is sold to the public, which adds economic value to the project.

“The treated water is pumped again through a pipeline network covering the whole of Dubai for use in irrigation of public parks and is sold to developers and farm owners, which also adds economic value to the project," said Al Rayes.

"Other products of the process include methane, which is planned to be used in the production of electricity, thus saving energy consumption from the public network and in line with Dubai's sustainability policy.

“The project currently employs more than 1,000 employees, including engineers, technicians, and labourers," he said.

He explained the expansion work has three main objectives, absorbing the excess influx from the planned Expo 2020 areas, keeping pace with the upcoming expansion projects in the emirate, and shifting a certain percentage of loads of Warsan plant to Jebel Ali plant, as it is running 27% above its design capacity.
